Xls Upd: Venturi Scrubber Design Calculation
Venturi scrubbers are highly effective wet scrubbing systems used primarily to remove fine particulate matter (PM) from industrial gas streams

is the Stokes number, a dimensionless parameter representing the ratio of the stopping distance of a particle to the characteristic dimension of the obstacle (the liquid droplet). Structuring the XLS Tool Input data : Enter the required input data,
- Input data: Enter the required input data, including gas flow rate, gas composition, particulate matter and gas concentrations, liquid flow rate, and liquid type.
- Calculate gas velocity: Calculate the gas velocity at the inlet of the venturi using the gas flow rate and duct diameter.
- Calculate throat velocity: Calculate the throat velocity of the venturi using the gas flow rate and throat diameter.
- Calculate pressure drop: Calculate the pressure drop across the venturi using the gas velocity, throat velocity, and duct diameter.
- Calculate collection efficiency: Calculate the collection efficiency of the scrubber using the particulate matter and gas concentrations, liquid flow rate, and pressure drop.
